sql server – Deadlock errors followed by Communication link failure and connection forcibly closed

The application log shows couple of exceptions indicating deadlocks:

The application has caught an exception. Query: select user,acc_data1,acc_data2 from user_acc_data, Exception: Transaction (Process ID 62) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. (Code: 40001, Microsoft SQL Server Native Client 11.0)

This is followed by errors shown below:

Example 1:

The application has caught an exception. Query: select user,acc_data1,acc_data2 from user_acc_data, Exception: TCP Provider: An existing connection was forcibly closed by the remote host. (Code: 08S01, Microsoft SQL Server Native Client 11.0)

Example 2:

The application has caught an exception. Query: select user,acc_data1,acc_data2 from user_acc_data, Exception: Communication link failure. (Code: 08S01, Microsoft SQL Server Native Client 11.0)

What could be the cause and whether the deadlock error could be responsible for the other 2 errors?

ssl – Will NGINX break any active connection when I revoke a specific client certificate with CRL?

Let’s assume I have a client (e.g. IOT1) connecting to MQTT broker behind NGINX instance (terminating TLS is nginx’s job) and I want to revoke that specific (IOT1) client, but what will happen with the connection? Will it be aborted or the connection will be still alive until the nginx or device will shutdown?

4.2 jelly bean – WIFI ON but Play fails “No internet connection. Make sure WiFi …”

Recently i decided to check for app updates and Play refuses to work and popup the error “No internet connection. Make sure WiFi or mobile data is turned on.”

However WIFI is enabled and internet work fine for apps like fdroid.

Maybe the issue is due to the fact that it is an old android 4.2 but Play services were updated 03/2019 and they are v 15.0.90

Is android 4 still supported by Play? ideas? other app stores?

And there are no alternatives as LineageOS or custom ROMs for this device

man in the middle – Tool for injecting data in existing tcp connection

I would like to perform arp spoofing on an existing tcp connection between a server and a client and perform a mitm attack. In addition to altering existing packets, I would like to be able to inject my own packets into the connection without disturbing the legitimate flow of packets. As I understand, this would require handling seq and ack numbers that are out of sync between the client and the server, as the server will receive more packets than the client sent. Is there a good tool for this?

Zoom in for MS SQL Server Database Connection screen

Problem:

When try to connect to SQL database, the SQL server database connection screen/page is too small to read. Is there any way to zoom in and make the form bigger?

I’m trying to test a JDBC connection from an AWS EC2 instance to a Centos 7 server running Oracle 12.2.0.1 and the connection is hanging

At some point we are going to upgrade our 12.2.0.1 databases to 19c, so I am using the 19c client on the EC2 instance for the JDBC drivers. When I try connecting to a 19c database it works. I am using Java 1.8.0_291 and the ojdbc8.jar library from the 19c Oracle Client.

Is there a reason why ojdbc8.jar won’t connect to a 12cR2 database? Is there something that
I can add to my listener on my 12cR2 database or to my pom.xml file that will allow this to work. Obviously, I can install a 12cR2 client and test that next. But I would like to understand why this is an issue first. I added a start trace to the Main.java file and compiled it with a stack trace. It takes over 5 minutes before it times out. Even though I reduced the timeout in the Main.java file.

Thanks

filezilla – laravel ftp connection error php_connect_nonb() failed: Operation now in progress

I want to create a Laravel app with a connection to my FTP server.
I have created it on my localhost and it works just fine without any error.
but when I uploaded it on my cPanel host I am getting an error :

ftp_rawlist(): php_connect_nonb() failed: Operation now in progress (115)

here is my filesystems.php file:

'cf1' => (
            'driver' => 'ftp',
            'host' => '185.xxx.xxx.5',
            'username' => 'xxxx',
            'password' => 'xxxx',
            'port' =>'21'
        ),

and for the test, I am calling allDirectories() function which leads to that error I already mentioned.
I also tried adding

'passive' => false,
'ignorePassiveAddress' => true,

to my FTP config, the error was gone but not any response either.
instead, my CPU usage went high and after a few seconds, it gave me a timeout error.

is there any cPanel config problem or even FileZilla FTP Server config that I have to check?
